Computer network security and to guard against
Abstract: When mankind entered the 21st century information society, the network society of the time, China will establish a complete set of network security system, especially from the policy and law to establish China's own characteristics, network security system.
Key words: computer; network; security; prevent
In the information age, information can help groups or indivials so that they benefit from, the same information can also be used to pose a threat to them, caused damage. Therefore network security, including the composition of network hardware, software and network transmission of information security, so that they do not because of accidental or malicious destruction of the attacks, network security not only the technical aspects, but also management issues, both complement each other, are indispensable.
First, the concept of computer network security
International Organization for Standardization of "computer security" is defined as: "To establish a data processing system and the adoption of technology and management of security protection, the protection of computer hardware, software, data is not e to accidental and malicious destruction of reasons, change and leakage." The above definition of computer security includes physical security and logical security of both the contents of the contents of the logic of security could be understood as we often say that the information security, information refers to the confidentiality, integrity and availability of protection, and network security Information security is the meaning of the extension, that network security is a network of information confidentiality, integrity and availability protection. Computer network security as the specific meaning of the user changes, the user is different on the network security awareness and requirements will be different. From the ordinary user's point of view, could only hope that personal privacy or confidential information transmission on the network be protected against eavesdropping, tampering and forgery; and network provider in addition to care about these network information security, we must also consider how to deal with sudden natural disasters, such as military strikes against the destruction of network hardware, as well as unusual in the network how to restore network communications, and maintain the continuity of network communications.
In essence, the network security, including the composition of network hardware, software and network transmission of information security, so that they do not because of accidental or malicious attacks on the destruction of both the technical aspects of network security issues, there are management issues, the two sides complement each other, are indispensable. Man-made network intrusion and attacks makes network security is facing new challenges.
Second, computer network security status quo
Computer network security is the network hardware, software and data systems are protected from accidental or malicious destruction of reasons, alteration, disclosure, the system continuous, reliable, normal operation of network services without disruption. Computer and network technology has the complexity and diversity, makes computer and network security has become a need to continue to update and improve the area. At present, hackers method has been more than the type of computer virus, and many attacks are fatal. In the Internet network, because the Internet does not have the time and geographical constraints, whenever there is a means to generate new attacks, we can in a week around the world, these attacks means the use of network and system vulnerabilities to attack computer systems and resulting in network paralysis. Worms, backdoor (Back-doors), Rootkits, DOS (DenialofServices) and Sniffer (network monitor) is a familiar means of several hacker attacks. However, none of these attacks means they reflect the astonishing power of today become worse. These types of attacks means the new variant, with previous attacks appeared methods, more intelligent, targeted against Internet-based protocols and operating system level. From the Web process control proceres to the kernel-level Rootlets. Hackers practices escalating renovation, to the user's ability to guard against information security challenge.
Third, computer network security precautions
1, to strengthen the internal network management and the use of safety awareness among staff, many computer systems commonly used passwords to control access to system resources, which is anti-virus process, the most vulnerable and the most economical methods. Network administrator and terminal operator privileges in accordance with their responsibilities, choose a different password for the application data legitimate operation, to prevent unauthorized users to access the data and the use of network resources.
On the network, software installation and management is crucial, it is not only related to network maintenance and management efficiency and quality, but also to the network security. A good antivirus software can be easily installed within minutes to the organization each NT server can also be downloaded and spread to all the purpose of the machine by the network administrator set up and manage to focus, it will work with the operating system and other security is closely linked to become a part of network security management, and automatically provide the best network virus defensive measures. When the computer virus on-line resources applications attack, such as the virus exists in the information-sharing network of media, it is necessary to the security at the gateway, on the network front-end for antivirus.
2, network firewall technology
Is a kind of used to strengthen the network access control to prevent the external network users to illegal means to enter the external network through the internal network, access internal network resources and protect the internal network operating environment special for Network Interconnection Devices. It is between two or more networks such as packet transmission link in accordance with a certain degree of security strategy to implement the inspection, to determine whether the network communication between are allowed to, and monitor the network running. Although the firewall is to protect the network from an effective means of hacking, but there are obviously inadequate: through the firewall can not protect against outside attack other means, can not prevent defectors from the inside and inadvertent threats posed by users, but also can not completely prevent the transmission of the virus have been infected with the software or documents, and can not protect against data-driven attacks.
3, security encryption technology
Encryption technology for the global e-commerce to provide a guarantee, so that Internet-based electronic trading system has become possible, thus improving the symmetric encryption and asymmetric encryption technology is still the mainstream of the 21st century. Symmetric encryption to the conventional password-based technology, computing encryption and decryption operations use the same key. Asymmetric encryption, encryption key that is different from the decryption key, encryption keys are made public, anyone can use, only the decryption key to decrypt people know.
4, the network host operating system security and physical security measures
Network firewall as the first line of defense and can not fully protect the internal network, must be combined with other measures to improve the safety of the system level. After the firewall is based on the network host operating system security and physical security measures. In accordance with the level from low to high, namely, the physical security of the host system, the core operating system security, system security, application services security and file system security; At the same time, host security checks and bug fixes, as well as a backup safety system as a supplementary safety measures. These constitute the entire network system, the second line of defense, the main part of a breakthrough to prevent the firewall as well as attacks from within. System backup is the last line of defense network system, used to attack after the System Restore. The firewall and host security measures is the overall system security by auditing, intrusion detection and response processor constitute the overall safety inspection and response measures. It from the network system firewall, network host or even directly from the network link layer on the extraction of network status information, as input to the intrusion detection subsystem. Intrusion Detection System in accordance with certain rules to determine whether there is any invasion of the incident, if the invasion occurred, the emergency treatment measures, and generate a warning message. Moreover, the system's security audit also can be used as the future consequences of aggressive behavior and to deal with security policy on the system to improve sources of information.
In short, network security is a comprehensive issue, involving technology, management, use and many other aspects, including both its own information system security issues, there are physical and logical technical measures, a kind of technology can only solve the problem on the one hand, rather than a panacea. To this end the establishment of a network with Chinese characteristics, security system, the need for national policies and regulations to support and joint research and development group. Security and anti-security like two sides of contradictions, always pick-up, so the security instry is a future with the development of new technologies and the continuous development of instry.

❸ 求一篇與網路安全有關的英語考研作文！
As the number of internet users continues to grow worldwide,internet safety is a growing concern for both children and alts. The internet safety, or online safety, is the knowledge of maximizing the user's personal safety and security risks on private information and property associated with using the internet, and the self-protection from computer crime in general.
To begin with, we have to take the information security into consideration. As we all know, sensitive information such as personal information and identity, passwords are often associated with personal property (for example, bank accounts) and privacy and may present security concerns if leaked. Unauthorized access and usage of private information may result in consequence such as identity theft, as well as theft of property.
What's more, the personal safety cannot be ignored. The growth of the internet gave rise to many important services accessible to anyone with a connection. One of these important services is digital communication. While this service allowed us to communicate with others through the internet, this also allowed the communication with malicious users. While malicious users often use the internet for personal gain, this may not be limited to financial/material gain. This is especially a concern to parents and children, as children are often targets of these malicious users.
How can we deal with the problems in the Internet safety? Actually, we have several preventions. First, keeping shared information at a minimum and safe passwords and PINs are useful. Moreover, we'd better strengthen our Social network websites and security software.
Through the use of antivirus software, the user can automatically detect, prevent and remove computer viruses and various types of malware. Very often it is impossible for the user alone to identify infected files and software until it is too late, especially if the infected file or software is well disguised as legitimate files. Because of this, it is important that the user keeps antivirus software running on the computer whenever accessing the internet so that the user can filter and block infected files and firewalls.

❹ 網路安全的英語作文
Recently, the news that U.S attack on China's Internet is always exposed. And the question of how to stay online safely raises a lot of discussion in our country. As a result, in the era of rapid development of network, we must take measures to protect our security of privacy and property effectively.
最近的新聞都揭示了美國對中國網路的攻擊。如何安全地上網在我國引起了大量的討論。結果是在網路飛速發展的時代，我們必須要採取有效的措施來保護我們的隱私和財產安全。
From my perspective, in the first place, we should call attention to our personal information. Not only do we not offer them at random in some strange websites, but we need to distinguish right from wrong among the numerous websites. Furthermore, it is inevitable that some secure anti-virus soft wares can be installed. And it will make it possible for that network can run more steadily. In addition to doing some work by ourselves, the government needs to draw up some policies to preserve national cyber security. It involves probing for deeply rooted reasons, devising creative solutions, developing high-tech talents and strengthening the supervision.
從我的角度來看，首先，我們應該關注我們的個人信息。我們不僅不隨隨便便在一些奇怪的網站提供自己的信息，而且我們需要在眾多的網站之間明辨是非。此外，安裝一些安全的殺毒軟體是必須的。這使得網路運行更加穩定。除了我們自己該做一些努力之外，還需要政府制定相關政策來保護國家網路安全。這就涉及到探究深層次的原因，想出有創造性的解決方案，發展高新技術人才、加強監管。
Although scientists still cannot overcome the problem completely, they are studying a great deal about how to protect our national cyber security. However, consciousness of cyber security should not decline. Only in this way, we just enjoy the convenience brought by the network.
盡管科學家仍無法完全克服這個問題，但是他們正在研究大量關於如何保護我們國家網路安全的辦法。然而，不應該放鬆網路安全意識。只有這樣我們才能享受到網路帶給我們的便利。
